This article will guide you through the process of generating a CSR on the following Mac operating systems: macOS Catalina, macOS High Sierra, and macOS Mojave. The CSR code generated will be utilized during the activation of your SSL certificate.
Important Note: If you are using the MacOS Server application you will need to follow the steps described in this article.
When using Keychain for CSR generation, locality, state and organization cannot be specified. If you would like to specify these details, you will need to generate a CSR using an online tool or the Terminal application as shown here instead.
